I don’t know if this is the correct section to put this under but here goes, maybe someone can give me some advice .
I had a little falling out with my MIL - we ran into SD mum at a local event (husband was never properly with sd mum, unplanned pregnancy but good relationship between husband and daughter)
Anyway - we did the civilised hellos for my step daughters sake. And then went our separate ways.
Whilst my husband and I took our son to a separate baby area (MIL & FIL stayed with SD in bigger child’s area)
My mil decided to go over to Sd mum , start up further conversation. When we returned we saw this , and her doing so then subsequently invited her over to our group. Which formed a very difficult and awkward situation for my husband& I
I wouldn’t mind if MIL had always said nice things about SD mum, but she has always slated her to the ground for past behaviours , always talks badly of her & her family to me (not around SD) and has always made her home a safe place to rant.
Therefore was then very awkward watching her then being so nice to SD mum, and I just couldn’t get over how two faced this was
This got my questioning the fact she talks this way about her and then is acting nice , does she do this about me.
Secondly I confronted her suggesting we’d said our hellos and that she’d put the rest of us in awkward situation by inviting her over and there wasn’t actually any need. It was my husbands time with his daughter - not hers . She indirectly apologised for “me feeling that way” and I later found out she then bad talked me to her family about this.
This was a few months ago, and I had thought , first and only disagreement - we’ve moved on.
However since then ... our relationship has been fragile , she is making more effort with SD mum, going round to her house to pick up SD but going in for a tea. Texting her more to ask to have SD more .
She is taking out step daughter but not inviting our son along. Having step daughter to stay at hers weekly - arranged through mum - without my husband knowing or around his own arrangements. He just says she has a right to do so , but I just find it so odd ? Surely he should be having the extra time with his daughter ?
I was such good friends with my mother in law before, and since this I am just surprised at how someone can say such awful things about someone and then act as if they’re friends& go to their house for tea!?! Any advice on how to move forward on this
